Marsh Bellofram Diversified Electronics Division TSD Series OFF-Delay Solid-State Output

Product catalog summary

Overview: The TSD Series 89 is a solid-state output device designed for off-delay timing applications. It operates by maintaining a continuous voltage input, with an external isolated switch controlling the timer. The load is energized when the switch is closed and de-energized after the delay period once the switch is opened.

Specifications:

Supply Voltage: Available in 120 or 240 VAC, 50/60 Hz with a tolerance of ±10%.
Output Rating: Solid-state, SPST-N.O. with 1 amp resistive; 1250 VA inrush, 125 VA run at 120 VAC, inductive.
Timing Ranges: Virtually unlimited, with standard ranges available on page 84.
Timing Tolerances: Minimum setting +0–20%, maximum setting ±10%.
Repeatability: 1% maximum, with no first cycle effect.
Reset Times: 100 mSEC before timeout, 50 mSEC after timeout.
Recycle Time: 40 mSEC.
Duty Cycle: Continuous.
Enclosure: Surface mounted and encapsulated with high-quality epoxy for environmental protection.
Temperature Rating: Operating range from 32° to 131°F (0° to +55°C), storage range from -49° to 185°F (-45° to +85°C).
Terminations: 1/4" quick disconnect terminals.
Weight: Net weight is 0.96 oz, shipping weight is 1.28 oz.

Operation: The device functions by energizing the load when the control switch is closed. Opening the switch starts the delay period, after which the load de-energizes. If the switch is reclosed during the delay, the timer resets to zero.

Model Numbering: The model number includes supply voltage, type of operation (fixed or external resistor adjustable), and delay period. An example model number is TSD-120-ARC-200, indicating a delay on release, 120 VAC, with an external resistor adjustable from 2 to 200 seconds.
